I'm a beginner and just bought my first board and bindings. On the binding box it read 6+. I assumed that was sizing info since there was nothing else about sizing on the box. My boot size is shaping out to be a 9 and I was wondering if I made the wrong purchase. I assumed 6+ meant sizes 6 and up. However when I got home and put them on I realized "SM" was etched into the back of the bindings which makes me think I bought smalls. Do I take them back? They're Sims brand if that helps.

I'm still waiting to get my boots. I ordered them online. My boyfriend said the same thing, to wait and see if the boots fit. However, is that a good indicator for a good fit, the strap being centered?
